As the penetration of renewable energy sources (RES) increases, the task of ensuring an instantaneous balance between energy supply and demand in a cost-effective manner becomes increasingly challenging. ‘Energy flexible’ buildings, where consumers make temporary adjustments to their consumption in response to an external request from the energy system, is a promising resource to assist in continually balancing energy supply and demand.

During his studies, Theis Friis Pedersen contributed to the development of a reliable economic model predictive control scheme suitable for application in existing residential buildings with a hydronic heating system. The objective of the control scheme is to exploit the thermal mass as a heat storage to shift the bulk of the space heating consumption to periods of e.g. high wind power production or low tariffs.

The research findings suggested that residential buildings can provide substantial balancing services to the energy system, while private householders simultaneously achieved thermal comfort and operational cost savings. The main outcome of the investigations amount to the recommendation of a two-level economic model predictive control setup.

The PhD degree was funded by ForskEL (EUDP) and completed at the Department of Engineering, Science and Technology, Aarhus University.
